Final answer:
The maximum possible number of support vectors for the new hyperplane is n + 1.
Step-by-step explanation:
When training a hard-margin linear SVM on n > 100 datapoints in R₂, the maximum number of support vectors for the hyperplane is n + 1. This means that if we add one more datapoint and retrain the classifier, the maximum possible number of support vectors for the new hyperplane is n + 1. In this case, since n > 100, the maximum possible number of support vectors for the new hyperplane would be greater than 100.
